News & Highlights

The Krishnan group is an experimental group focused on the structural, magnetic, optical and transport properties of colloidal inorganic nanostructures, hybrid materials, thin films and lithographically patterned heterostructures. Our research occurs at the bio-nano-medical, magneto-electronic, and nano-energy interfaces.
